    • High-purity distyryl benzene (DSB) is synthesized, purified, and used in the construction of lasers operable in the blue-violet spectral range. The laser action is easily tuned. Crystal growth is based on a physical vapor transport (PVT) technique preferably using argon, hydrogen or "forming gas" as the transport agent. Synthesis involves the use of a lithium ethoxide-promoted Wittig condensation between 1, 4-bis (triphenylphosphonium) benzene and benzaldehyde. A 15-minute treatment follows using a catalytic amount of iodine in refluxing toluene. A sequential purification of the DSB material involving a recrystallization from hexane solution, followed by vacuum distillation, is preferably undertaken prior to single-crystal growth. The resulting laser action occurs generally in the blue spectral range, and may occur at multiple bands, for example, at 442 nm and 470 nm. The laser action may also be tuned as a function of temperature, for example, from 441 to 446 nm,, or 468 to 474 nm. Tuning of polarization or other optical properties may also be achieved. The material may further be macrotuned by switching between two phonon side bands. Lasing by carrier injection is also possible, and alloys of longer PPV oligomers (n>3) in DSB may be grown into single crystals to give tunable laser action in the green-yellow spectral range.
    • 高纯度二苯乙烯基苯(DSB)被合成,纯化,用于建立在蓝紫色光谱范围内可操作的激光器。 激光作用很容易调整。 晶体生长基于优选使用氩气,氢气或“形成气体”作为运输剂的物理蒸汽输送(PVT)技术。 合成涉及在1,4-双(三苯基鏻)苯和苯甲醛之间使用乙醇锂促进的维t缩缩。 使用催化量的碘在回流的甲苯中进行15分钟的处理。 包括从己烷溶液重结晶,然后真空蒸馏的DSB材料的顺序纯化优选在单晶生长之前进行。 所产生的激光作用通常发生在蓝色光谱范围内,并且可能发生在多个带,例如在442nm和470nm处。 也可以将激光作用调节为温度的函数,例如,从441至446nm,或468至474nm。 也可以实现极化或其他光学特性的调谐。 通过在两个声子边带之间切换,该材料还可进一步宏观调节。 通过载流子注入也可以进行激光,DSB中更长的PPV低聚物(n> 3)的合金可以生长成单晶,以在绿黄色光谱范围内提供可调谐的激光作用。

    • A method of reacting a first compound to produce a second compound includes the step of contacting a first non-fluorous phase including the first compound with a first fluorous phase at a first phase interface. The first compound distributes between the first fluorous phase and the first non-fluorous phase. The method further includes the steps of contacting the first fluorous phase with a second non-fluorous phase at a second phase interface and including at least a third compound in the second non-fluorous phase that reacts with the first compound to produce the second compound. The second compound has a distribution coefficient less than the first compound. This method can, for example be used to separate the second compound from unreacted first compound wherein, for example, the first compound is of a fluorous nature and distributes more readily into (or transports more quickly through) the fluorous phase than does the second compound. In general, the fluorous phase serves as a barrier to prevent the two non-fluorous phases from mixing, but molecules that can migrate through the fluorous phase can pass from one side to the other.
    • 使第一化合物反应以产生第二化合物的方法包括使第一化合物的第一非氟相与第一相界面处的第一氟相接触的步骤。 第一化合物在第一氟相和第一非氟相之间分配。 该方法还包括以下步骤:在第二相界面处使第一氟相与第二非氟相接触,并且在第二非氟相中包含至少第三化合物,其与第一化合物反应以产生第二化合物。 第二化合物的分配系数小于第一化合物。 该方法可以例如用于将第二化合物与未反应的第一化合物分离,其中例如第一化合物具有氟性质,并且比第二化合物更容易地分配(或更快地通过)氟相 。 通常,氟相用作防止两个非氟相混合的屏障,但是可以迁移穿过氟相的分子可以从一侧传递到另一侧。
